Copolymerization of vinyl acetate with maleic anhydride and N,N-dimethylaminoethyl methacrylate

Copolymerization of vinyl acetate with maleic anhydride and N,N-dimethylaminoethyl methacrylate. Abramyan, R. K.; Golubkova, E. V. (Yarosl. Politekh. Inst., Yaroslavl, USSR). Vysokomol. Soedin., Ser. B, 26(1), 23-5 (Russian) 1984. CODEN: VYSBAI.Some commonly used reagents like 108-31-6 and 2867-47-2 are used in this experiment. ISSN: 0507-5483. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Vinyl acetate (I) [108-05-4] was copolymd. with maleic anhydride (II) [108-31-6] in dioxane at 60 ± 0.5° and with (dimethylamino)ethyl methacrylate (III) [2867-47-2] in iso-PrOH at 70 ± 0.5°. AIBN was used as initiator in both cases. The ratio of the polymn. decreased with increasing initial concn. of I in the reaction mixt. (total initial monomer concn. 2 mol/L). The exptl. detd. monomer reactivity ratios for the copolymn. of I with II were r1 = 0.2755 ± 0.0634 and r2 = 0.0031 ± 0.0001, and of I with III r1 = 0.0301 ± 0.0001 and r2 = 0.0576 ± 0.0001, resp. The corresponding monomer reactivity ratios calcd. from the Q-e values reported in the literature were for I-II r1 = 0.0656 and r2 = 0.0034, and for I-III r1 = 0.0328 and r2 = 18.91. The obsd. discrepancy between both sets of data was ascribed to complex formation. .
